Graph ABCD with vertices B(2, 1), C(4,4) and D(4,0) and its image after the reflection in the line n: x=0.

Graph ABCD With Vertices B2 1 C44 And D40 And Its Image After The Reflection In The Line N X0 class=

Sagot :

We have a triangle BCD with vertices

[tex]\lbrace(2,1),(4,4),(4,0)\rbrace[/tex]

The transformation is a reflection in the line x = 0(also know as the y-axis). A reflection on the y-axis is given by the following transformation:

[tex](x,y)\rightarrow(-x,y)[/tex]

Doing this transformation on each one of our vertices, we can find the transformed figure.

[tex]\begin{gathered} (2,1)\rightarrow(-2,1) \\ (4,4)\rightarrow(-4,4) \\ (4,0)\rightarrow(-4,0) \end{gathered}[/tex]

Then, the image is

[tex]\lbrace(-2,1),(-4,4),(-4,0)\rbrace[/tex]

The option that fits this transformation is option b.
